Brief description of potassium sulfate materials: colorless or white crystals, granules or powders. Odorless. Bitter taste. Hard quality. Stable in air. 1g is soluble in 8.3ml water, 4ml boiling water and 75ml glycerol, but insoluble in ethanol. Potassium chloride and ammonium sulfate can increase their solubility in water, but they are almost insoluble in the saturated solution of ammonium sulfate. The water solution is neutral with a pH of about 7. The relative density is 2.66. The melting point is 1067 C. The main uses include serum protein biochemical test, Kjeldahl nitrogen determination catalyst, preparation of other potassium salts, fertilizers, drugs, preparation of glass, alum and so on. Function and Use of Potassium Sulfate Material: It is the basic material for making various potassium salts such as potassium carbonate and potassium persulfate. The glass industry is used as a detergent. The dyestuff industry is used as an intermediate. The perfume industry is used as auxiliaries, etc. Pharmaceutical industry is also used as laxatives. Potassium sulfate is commonly used as a potassium fertilizer in agriculture. Its potassium content is about 50%. It is commonly called Baikali in Taiwan. In addition, potassium sulfate is also used in industry for glass, dyes, spices, medicine and so on.

The working principle of potassium sulphate special disc dryer: wet material is continuously added to the first layer of drying plate on the upper part of the dryer by self-feeder, and the rake arm with rake blade rotates to make the rake arm rotate to make the rake blade turn over the material continuously. Material flows through the surface of the drying tray along the exponential helix. Material on the small drying tray is transferred to the outer edge and falls to the outer edge of the large drying tray below. Material on the large drying tray moves inward and falls from the middle outlet into the following small drying tray. The large and small drying pans are arranged alternately up and down, so that the material can flow continuously through the whole dryer. A heating medium is introduced into the hollow drying plate, which is in the form of saturated steam, hot water and heat conducting oil. The heating medium enters from one end of the drying plate and is derived from the other end. The dried material falls from the last drying plate to the bottom of the shell, and is eventually transferred to the discharging port by the rake blade. The moisture escapes from the material and is discharged from the dehumidification outlet on the top cover. The moisture of the vacuum disk dryer is discharged from the vacuum pump outlet on the top cover. Dry materials discharged from the bottom can be packed directly. By adding fin heater, solvent recovery condenser, bag filter, dry material back mixing mechanism, induced draft fan and other auxiliary machines, the drying capacity can be improved, paste and heat sensitive materials can be dried, solvents can be easily recovered, and pyrolysis and reaction operation can be carried out.

Summary: Disc continuous dryer is an efficient conductive continuous drying equipment. Its unique structure and working principle determine that it has the characteristics of high thermal efficiency, low energy consumption, small floor area, simple configuration, convenient operation and control, and good operating environment. Widely used in chemical industry, medicine, pesticides, food, feed, agricultural by-products processing and other industries of drying operations. It is well received in the use practice of various industries. It can be divided into three types: atmospheric pressure, airtight and vacuum; 1200, 1500, 2200, 3000 and other specifications; A (carbon steel), B (stainless steel in contact with materials), C (on the basis of B), adding steam pipeline, spindle and bracket to stainless steel, cylinder and top cover lined stainless steel), three materials, drying area 4-180 m2, a total of several hundred types of products, and can provide matching products. Auxiliary equipment can meet the needs of users for drying various materials.

Features (1) Easy regulation and strong applicability. 1. The drying process can be optimized by adjusting the thickness of material layer, spindle speed, number of rake arms, rake blade type and size. 2. Each layer of drying tray can be heated or cooled by heat or cold medium. The material is heated evenly and the temperature control is accurate and easy. 3. The residence time of materials can be adjusted accurately. 4. Material flow direction is single, no backmixing phenomenon, uniform drying, stable quality, no need for re-mixing. (2) It is easy to operate. 1. The operation of starting and stopping the dryer is very simple. 2. After stopping feeding, the rake blade which conveys the material can quickly empty the material in the dryer. 3. Through the special large size inspection door mirror, the equipment can be very carefully cleaned and observed. (3) Low energy consumption 1. The material layer is very thin, the spindle speed is low, and the material transmission system needs less power and power consumption. 2. Drying by conductive heat has high thermal efficiency and low energy consumption. (4) Good operating environment, recoverable solvents, dust emissions meet the requirements 1. Atmospheric pressure type: Because of the low airflow speed in the equipment and the high and low humidity distribution in the equipment, dust is difficult to float to the top of the equipment, so the exhaust gas discharged from the top dehumidifier contains almost no dust. 2. Closed type: equipped with solvent recovery device, can easily recover organic solvents in wet gas. Solvent recovery device is simple and the recovery rate is high. For flammable, explosive, toxic and oxidizable materials, nitrogen can be used as a wet gas for closed-circuit circulation to make it safe to operate. It is especially suitable for drying flammable, explosive and toxic materials. 3. Vacuum type: Disk dryer operated in vacuum, especially suitable for drying heat-sensitive materials. (5) Installation is convenient and occupies a small area. 1. The dryer is manufactured as a whole and transported as a whole. It only needs to be hoisted in place. The installation and positioning are very easy. 2. Because of drying
